  Gyroscopic motion is angular momentum; since a body can have momentum and not have linear motion, gyroscopes "store" momentum (energy).
  
  This is why a gyroscope maintains a fixed orientation when you transport it (say, around a sphere). The angular momentum around a fixed axis, stays fixed according the Newton's laws, just like linear momentum does - except linear momentum distributes energy, angular momentum "keeps" energy in place.
